The variable source already seems to be declared on line 1. Consider using another variable name or omitting the var keyword.
This check looks for variables that are declared in multiple lines. There
may be several reasons for this.
In the simplest case the variable name was reused by mistake. This may lead to
very hard to locate bugs.
If you want to reuse a variable for another purpose, consider declaring it
at or near the top of your function and just assigning to it subsequently so
it is always declared.
